How to Choose the Right Sensor Module?
When selecting a module, always consider the operating voltage (3.3V vs. 5V) to match your mainboard and prevent hardware damage. Additionally, verify the required output type—analog signals or digital interfaces like I2C, SPI, and I2S—to ensure full compatibility with your existing circuitry and programming libraries.
